Description

Technical Field

[0001] The utility model relates to the technical field of circuit board equipment, in particular to a single-body opening and closing guard plate frame device. Background Art

[0002] Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis, thereby preventing metal oxidation, improving wear resistance, conductivity, reflectivity, corrosion resistance, and enhancing aesthetics. With the continuous reduction in the size of electronic products and the strengthening of the lightweight trend, circuit boards are becoming thinner and thinner.

[0003] In the horizontal electroplating line of circuit boards, a lifting mechanism is usually used to drive the circuit board hanger holding the circuit board to enter the liquid medicine pool vertically, so that the circuit board contacts the liquid medicine in the liquid medicine pool for electroplating. Due to the presence of a certain liquid tension on the surface of the liquid medicine, the circuit board will be affected by the liquid tension and bend and deform when entering the liquid medicine. The thinner the circuit board, the smaller its cross-sectional area, and the more concentrated the liquid tension is, resulting in a greater degree of bending and deformation of the circuit board. The current lifting mechanism usually directly brings the circuit board vertically into the liquid medicine pool, resulting in a large degree of deformation of the circuit board.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0030] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0031] Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis, thereby preventing metal oxidation, improving wear resistance, conductivity, reflectivity, corrosion resistance, and enhancing aesthetics. With the continuous reduction in the size of electronic products and the strengthening of the lightweight trend, circuit boards are becoming thinner and thinner.

[0032] In the horizontal electroplating line of circuit boards, a lifting mechanism is usually used to drive the circuit board hanger holding the circuit board to enter the liquid medicine pool vertically, so that the circuit board contacts the liquid medicine in the liquid medicine pool for electroplating. Due to the presence of a certain liquid tension on the surface of the liquid medicine, the circuit board will be affected by the liquid tension and bend and deform when entering the liquid medicine. The thinner the circuit board, the smaller its cross-sectional area, and the more concentrated the liquid tension is, resulting in a greater degree of bending and deformation of the circuit board. The current lifting mechanism usually directly brings the circuit board vertically into the liquid medicine pool, resulting in a large degree of deformation of the circuit board.

[0033] In addition, the existing guard frame is usually used for multiple circuit board liquid immersion stations at the same time, that is, the guard frame protects multiple circuit boards from entering the liquid pool at the same time. Since the height of this type of guard frame is fixed, it cannot be used for circuit boards of various lengths or heights.

[0034] To solve the above problems, please refer to Figures 1 to 3 The utility model proposes a single-body opening and closing guard plate frame device 100, which includes a guard plate frame assembly 110, and the guard plate frame assembly 110 is used to reduce the deformation of the circuit board in the medicine pool; the bottom plate 120, the bottom plate 120 and the guard plate frame assembly 110 enter the medicine pool in turn, and the bottom plate 120 is used to destroy the surface tension of the liquid in the medicine pool.

[0035] In this embodiment, a bottom plate 120 is provided, and the bottom plate 120 is located on the side of the guard plate frame assembly 110 close to the medicine pool. When the guard plate frame assembly 110 enters the medicine pool along with the circuit board, the bottom plate 120 first contacts the liquid surface in the medicine pool, thereby destroying the liquid tension, reducing the liquid tension on the circuit board, and thus reducing the degree of bending of the circuit board caused by the tension.

[0036] It should be noted that the plate guard frame assembly 110 is used to reduce the impact of liquid fluctuations or shocks generated by the liquid in the medicine pool on the circuit board.

[0037] It should be noted that Figure 1For reference, the X-axis direction is the direction in which the circuit board rack moves into the guard frame assembly 110, the Z-axis direction is the direction in which the guard frame assembly 110, the circuit board rack and the circuit board enter the potion pool, and the Y-axis direction is perpendicular to the X-axis and Z-axis directions. After the circuit board rack moves along the X-axis and enters between the guard frame assembly 110, the guard frame assembly 110 and the circuit board rack move along the Z-axis direction, and the guard frame assembly 110 protects the circuit board from entering the potion pool, so that the circuit board completes the reaction in the potion pool.

[0038] In one embodiment, please refer to Figures 1 to 3 The bottom plate 120 includes two inclined portions 122 , and the two inclined portions 122 are inclined with respect to each other.

[0039] In one embodiment, please refer to Figure 5 The bottom plate 120 further includes a perforated portion 123 , one end of the two inclined portions 122 are mutually inclinedly connected to the perforated portion 123 , and the perforated portion 123 is penetrated by a through hole 123 a .

[0040] In this embodiment, one end of the two inclined portions 122 is mutually inclined and connected to the perforated portion 123, and the two inclined portions 122 and the perforated portion 123 are roughly in a trapezoidal shape, that is, the area along the perforated portion 123 toward the inclined portion 122 increases successively. When the bottom plate 120 enters the liquid pool and contacts the liquid, the perforated portion 123 contacts the liquid before the inclined portion 122. Since the perforated portion 123 has a smaller area, the tension it is subjected to is small, and the perforated portion 123 destroys part of the surface tension of the liquid, which facilitates the inclined portion 122 to further contact the liquid surface and destroy the surface tension of the liquid, thereby achieving the function of protecting the circuit board.

[0041] Furthermore, the coordinate of the bottom plate 120 on the Y-axis is the same as the coordinate of the circuit board on the Y-axis when it is located in the guard frame assembly 110, that is, the bottom plate 120 and the circuit board are located in the same plane, thereby ensuring that the tension on the liquid surface is destroyed when the circuit board enters the liquid surface.

[0042] In one embodiment, please refer to Figures 1 to 3 A groove 121 is provided at one end of the inclined portion 122 away from the perforated portion 123 , and a groove wall of the groove 121 is used to connect with the guard plate frame assembly 110 .

[0043] In this embodiment, the groove wall of the groove 121 is connected to the guard plate frame assembly 110, and the bottom plate 120 is extended along the X-axis direction. The bottom plate 120 is arranged along the X-axis direction to increase the contact area between the bottom plate 120 and the liquid surface, thereby better destroying the tension of the liquid surface and further reducing the influence of the tension on the circuit board.

[0044] In this embodiment, the guard plate frame assembly 110 includes a connecting piece, which is partially located in the groove 121, and the bottom plate 120 is fixedly connected to the guard plate frame assembly 110 by welding or other methods to prevent the bottom plate 120 from falling off the guard plate frame assembly 110. In other embodiments, the connection method between the bottom plate 120 and the guard plate frame assembly 110 is not limited.

[0045] In this embodiment, the perforated portion 123 is provided with a through hole 123a along the Z-axis direction, which reduces the resistance of the bottom plate 120 when entering the liquid without affecting the bottom plate 120 from destroying the surface tension of the liquid, so that the bottom plate 120 can smoothly enter the medicine pool.

[0046] In one embodiment, please refer to Figure 1 to Figure 2 The guard plate frame assembly 110 includes a first guard plate frame 112 and a second guard plate frame 113. The guard plate frame assembly 110 includes a first guard plate frame 112 and a second guard plate frame 113. The first guard plate frame 112 is close to the second guard plate frame 113, so that the first guard plate frame 112 and the second guard plate frame 113 are respectively located on both sides of the circuit board.

[0047] In this embodiment, the first guard plate frame 112 moves along the Y-axis toward the second guard plate frame 113, so that the first guard plate frame 112 and the second guard plate frame 113 are respectively located on both sides of the circuit board to reduce the deformation of the circuit board in the medicine pool.

[0048] It should be noted that the reason why the circuit board is deformed in the medicine pool is that the liquid in the medicine pool will generate liquid fluctuations or impacts in an unstable state. The fluctuations or impacts are dispersedly applied to the circuit board, making it easy for thin or soft circuit boards to twist, deflect or flutter, thereby causing the circuit board to deform. Therefore, the first guard plate frame 112 and the second guard plate frame 113 are set on both sides of the circuit board to reduce the deformation space of the circuit board, thereby avoiding the circuit board from deforming.

[0049] In one embodiment, please refer to Figures 1 to 3 The guard plate frame assembly 110 also includes a fixing frame 114, the first guard plate frame 112 is slidably connected to the fixing frame 114, the second guard plate frame 113 is connected to the fixing frame 114, and the fixing frame 114 is used to drive the first guard plate frame 112 and the second guard plate frame 113 into the medicine pool.

[0050] Specifically, the first guard plate frame 112 includes a first connecting rod 1121, and a sliding rail and a slider are provided in the fixed frame 114. The sliding rail is extended along the Y-axis direction, and the slider is slidably connected to the sliding rail. The slider is connected to the first connecting rod 1121, and the slider moves along the sliding rail, thereby driving the first guard plate frame 112 to approach or move away from the second guard plate frame 113. The second guard plate frame 113 includes a second connecting rod 1131, and the second connecting rod 1131 is fixedly connected to the fixed frame 114.

[0051] In this embodiment, the fixing frame 114 sets a separate guard plate frame assembly 110 on the production line. By setting up multiple fixing frames 114, the guard plate frame assembly 110 on each fixing frame 114 operates independently, thereby protecting circuit boards of different lengths or heights from entering the medicine pool, thereby improving the flexibility of the present invention.

[0052] In addition, the first connecting rod 1121 , the second connecting rod 1131 and the fixing frame 114 are provided with an insulating device 140 to prevent the current in the liquid from entering the fixing frame 114 and affecting the normal operation of other components in the fixing frame 114 .

[0053] In one embodiment, a sensing device (not shown in the figure) is provided on the fixing frame 114 , and the sensing device is used to detect whether there is a circuit board between the first guard plate frame 112 and the second guard plate frame 113 .

[0054] In this embodiment, the single-body opening and closing guard plate frame device 100 also includes a driving source, which is used to drive the fixed frame 114 to move along the Z axis. When the sensing device senses the presence of a circuit board between the guard plate frame assembly 110, the driving source is controlled to drive the fixed frame 114 to move along the Z axis direction into the medicine pool.

[0055] In one embodiment, please refer to Figures 1 to 4 The guard plate frame assembly 110 further includes a plurality of guide members 130 , and the plurality of guide members 130 are located on a side of the first guard plate frame 112 and the second guard plate frame 113 close to the circuit board.

[0056] In one embodiment, please refer to Figure 4 The guide member 130 includes a guard plate portion 132 and a bent portion 133 connected to each other. The guard plate portion 132 is used to abut against the circuit board. The bent portion 133 is located at one end of the guard plate portion 132 and has a certain curvature.

[0057] In this embodiment, in order to allow the circuit board hanger to smoothly enter the guard plate frame assembly 110, the two oppositely disposed bent portions 133 are bent in a direction away from the circuit board, that is, the two oppositely disposed bent portions 133 form a V-shaped opening, the size of the opening gradually decreases along the direction in which the bent portion 133 approaches the guard plate portion 132, and is used to guide the circuit board into between the two guard plate portions 132. In addition, the guard plate portion 132 is arranged as close to the circuit board as possible, which can also protect the circuit board in the subsequent spraying process and reduce the probability of deformation of the circuit board.

[0058] In one embodiment, please refer to Figure 1 and Figure 2The guide member 130 also includes a mounting portion 131 connected to the guard plate portion 132, and the mounting portion 131 is located on the side of the guard plate portion 132 away from the circuit board. The bolt passes through one side of the mounting portion 131, the first guard plate frame 112 or the second guard plate frame 113 and the other side of the mounting portion 131 in sequence and is connected to the nut, so that the guide member 130 is connected to the first guard plate frame 112 or the second guard plate frame 113.

[0059] In this embodiment, the guide member 130 is detachably mounted on the first guard plate frame 112 or the second guard plate frame 113 by the cooperation of bolts and nuts, so that the guide member 130 can be quickly disassembled and quickly assembled. When the guide member 130 needs maintenance or replacement, the steps of disassembly and assembly are simplified.

[0060] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
